DETAILED DESCRIPTION OF THE INVENTION

To facilitate understanding of the object, characteristics and effects of this present disclosure, embodiments together with the attached drawings for the detailed description of the present disclosure are provided.

Referring to FIG. 1 through FIG. 3, the present disclosure provides a structure conducive to reduction of fastening element height, comprising a fastener 1 and a body portion 2.

The fastener 1 has a head portion 11, a fastening portion 12, a rod portion 13, a resilient component 14 and a resilient component placement portion 15.

The body portion 2 and the fastener 1 are movably fitted together.

In a preferred embodiment of the present disclosure, the head portion 11 is disposed at one end of the rod portion 13, and the fastening portion 12 is disposed at the other end of the rod portion 13. The resilient component placement portion 15 is disposed within the fastening portion 12. The rod portion 13 is partially placed within the resilient component placement portion 15. The resilient component 14 is placed within the resilient component placement portion 15. The resilient component 14 has one end abutting against the body portion 2 and the other end abutting against the resilient component placement portion 15.

To start using the structure conducive to reduction of fastening element height, a user fits the body portion 1 to a first object 10 and fastens the fastening portion 12 of the fastener 1 to a second object 20. After the fastening portion 12 has been fastened to the second object 20, the user exerts a force on the head portion 11 and pulls the head portion 11 upward, such that the head portion 11, the fastening portion 12 and the rod portion 13 move upward. Then, the user compresses the resilient component 14, such that the resilient component 14 is stored in the resilient component placement portion 15; consequently, when the resilient component 14 retracts, the resilient component placement portion 15 nullifies retraction height of the resilient component 14 to reduce corresponding height of the body portion 2. After the second object 20 has been disposed at the fastening position, the user releases the head portion 11, such that the fastening portion 12 and the rod portion 13 move downward simultaneously; consequently, the resilient component 14 is resiliently released and thus fastens the fastening portion 12 to the second object 20. To remove the fastening portion 12 from the second object 20, the user exerts a force on the head portion 11 to pull the head portion 11 upward, such that the head portion 11, the fastening portion 12 and the rod portion 13 move upward, and then the user compresses the resilient component 14, such that the fastening portion 12 is fastened to the second object 20 for removal thereof. Therefore, in this embodiment, the head portion 11 is a vertically movable pull member, and vertical motion of the head portion 11 causes the fastening portion 12 to move toward the body portion 2 and thus can be fastened to the second object 20 and removed from the second object 20, thereby allowing at least two objects (the first object 10 and the second object 20) to be coupled together and separated repeatedly and rapidly.

In a preferred embodiment of the present disclosure, the body portion 2 has a fitting portion 21. The fitting portion 21 is adapted to be fitted to the first object 10. Therefore, the fitting portion 21 enables the body portion 2 to be firmly disposed at the first object 20, such that the fastening portion 12 of the fastener 1 enables the first object 10 and the second object 20 to be firmly fitted together. Therefore, the present disclosure meets practical needs.

In a preferred embodiment of the present disclosure, the resilient component placement portion 15 is a dent recess, dent hole or dent portion, and the rod portion 13 is partially placed within the dent recess, dent hole or dent portion of the resilient component placement portion 15. Moreover, the resilient component placement portion 15 is a storage space defined by the fastening portion 12 and the body portion 2 or a storage space defined by the rod portion 13 and the body portion 2. Therefore, when the resilient component 14 retracts, the resilient component placement portion 15 nullifies retraction height of the resilient component 14 to reduce corresponding height of the body portion 2.

In a preferred embodiment of the present disclosure, the head portion 11 and the rod portion 13 are integrally formed or fitted together. The rod portion 13 and the fastening portion 12 are integrally formed or fitted together. The head portion 11, the rod portion 13 and the fastening portion 12 are integrally formed or fitted together. Therefore, the present disclosure meets practical needs.

In a preferred embodiment of the present disclosure, the fastening portion 12 is a cylinder member (such as part a of FIG. 3), thread member (such as part b of FIG. 3), inner fastener (such as part c of FIG. 3), outer fastener (such as part d of FIG. 3) or resilient fastener. Therefore, the present disclosure meets practical needs.

In a preferred embodiment of the present disclosure, the resilient component 14 is a helical spring, leaf spring, torsional spring, resilient cylinder member or storage spring. Therefore, the present disclosure meets practical needs.

In a preferred embodiment of the present disclosure, the head portion 11 and the rod portion 13 or the head portion 11 and the fastening portion 12 are fitted together by screwing, riveting, expanding or fastening. Therefore, the present disclosure meets practical needs.

In a preferred embodiment of the present disclosure, an end portion 151 of the resilient component placement portion 15 and the body portion 2 are fitted to each other to define placement space height a of the resilient component placement portion 15. The placement space height ranges from 0.05 mm to 500 mm. Therefore, the present disclosure meets practical needs.

In a preferred embodiment of the present disclosure, the body portion 2 has a blocking portion 22 for blocking the resilient component 14 and the resilient component placement portion 15. The blocking portion 22 is a flat surface portion, stepped portion, dent portion, raised portion, oblique surface portion, arcuate surface portion or curved surface portion. Therefore, the present disclosure meets practical needs.

Referring to FIG. 4, in a preferred embodiment of the present disclosure, the head portion 11 is a rotatable operable member. The user moves the head portion 11 upward, such that the head portion 11, the fastening portion 12 and the rod portion 13 move upward to thereby compress the resilient component 14, such that the resilient component 14 is stored in the resilient component placement portion 15; consequently, when the resilient component 14 retracts, the resilient component placement portion 15 nullifies retraction height of the resilient component 14 to reduce corresponding height of the body portion 2. After the second object 20 has been disposed on the fastening position, the user moves the head portion 11 downward to allow the fastening portion 12 and the rod portion 13 to move downward simultaneously; consequently, the fastening portion 12 is fastened to the second object 20, and the resilient component 14 is resiliently released. To remove the fastening portion 12 from the second object 20, the user moves the head portion 11 upward, such that the head portion 11, the fastening portion 12 and the rod portion 13 move upward and compress the resilient component 14, allowing the fastening portion 12 to be removed from the second object 20. Therefore, the fastening portion 12 can be fastened to the second object 20 and removed from the second object 20, thereby allowing at least two objects (the first object 10 and the second object 20) to be coupled together and separated repeatedly and rapidly.

Referring to FIG. 5 and FIG. 6, in a preferred embodiment of the present disclosure, the head portion 11 is a laterally movable sliding member and has a receiving portion 111 and a limiting portion 112 which are in communication with each other, whereas the rod portion 13 has an abutting portion 131. Therefore, to start using the structure conducive to reduction of fastening element height, the user moves the head portion 11 laterally, such that the limiting portion 112 of the head portion 11 pushes the abutting portion 131 of the rod portion 13, and the limiting portion 112 restricts the abutting portion 131 to the pull position; consequently, the fastening portion 12 and the rod portion 13 move upward and compress the resilient component 14, such that the resilient component 14 is stored in the resilient component placement portion 15. Consequently, when the resilient component 14 retracts, the resilient component placement portion 15 nullifies retraction height of the resilient component 14 to reduce corresponding height of the body portion 2. After the second object (not shown) has been disposed on the fastening position, the user moves the head portion 11 laterally, such that the abutting portion 131 of the rod portion 13 enters the receiving portion 111 of the head portion 11. As a result, the fastening portion 12 and the rod portion 13 move downward simultaneously to thereby fasten the fastening portion 12 to the second object and allow the resilient component 14 to be resiliently released. To remove the second object, the user moves the head portion 11 laterally, such that the limiting portion 112 of the head portion 11 pushes the abutting portion 131 of the rod portion 13, whereas the limiting portion 112 restricts the abutting portion 131 to the pull position. Consequently, the fastening portion 12 and the rod portion 13 move upward and compress the resilient component 14. Therefore, the fastening portion 12 can be fastened to and removed from the second object, thereby allowing at least two objects (the first object 10 and the second object) to be coupled together and separated repeatedly and rapidly.

Referring to FIG. 7 and FIG. 8, in a preferred embodiment of the present disclosure, the resilient component 14 is a storage spring. The head portion 11 is pulled upward, such that the head portion 11, the fastening portion 12 and the rod portion 13 move upward and compress the resilient component 14. Consequently, the resilient component 14 manifests a linear height and is stored in the resilient component placement portion 15. Therefore, the present disclosure meets practical needs.

Referring to FIG. 9 and FIG. 10, in a preferred embodiment of the present disclosure, the head portion 11, the resilient component placement portion 15 and the rod portion 13 not shown) function as a fastening portion adapted to be fastened to the second object 20, and the resilient component placement portion 15 is a blocking portion (or the blocking portion and the body portion 2 define a storage space). The end portion 151 of the resilient component placement portion 15 and the body portion 2 are fitted to each other to define placement space height a of the resilient component placement portion 15. As shown in FIG. 9, the resilient component placement portion 15 is a stepped portion. As shown in FIG. 10, the resilient component placement portion 15 is a flat surface portion, and the blocking portion 22 of the body portion 2 is a stepped portion.
